Show/Hide hidden formatting symbols like paragraph markers in RichTextBox control

Does anyone know how to display the 'paragraph marks' or other hidden formatting symbols in the RicthTextBox control for WPF? I see the Telerik Editor (RichTextBox) has a button on their toolbar for toggling the display of such symbols in the editor.

We have a custom editor we built in our application, which was built using the RichTextBox control that ships with Visual Studio in WPF and we have a user request to add the capability to show/hide these hidden formatting symbols.

I have not found a setting for the RichTextBox control to turn on this display and have not found any posting yet on how to accomplish this. Seeing this feature in the Telerik RadRichTextBox controls tells me that it can be done, but I don't know how to implement it myself.
